| 2 | |
| 3 | Required properties: |
| 4 | |
| 5 | - compatible: should be "amazon,al-fic" |
| 6 | - reg: physical base address and size of the registers |
| 7 | - interrupt-controller: identifies the node as an interrupt controller |
| 8 | - #interrupt-cells : must be 2. Specifies the number of cells needed to encode |
| 9 | an interrupt source. Supported trigger types are low-to-high edge |
| 10 | triggered and active high level-sensitive. |
| 11 | - interrupts: describes which input line in the interrupt parent, this |
| 12 | fic's output is connected to. This field property depends on the parent's |
| 13 | binding |
| 14 | |
| 15 | Please refer to interrupts.txt in this directory for details of the common |
| 16 | Interrupt Controllers bindings used by client devices. |

| 18 | Example: |
| 19 | |
| 20 | amazon_fic: interrupt-controller@fd8a8500 { |
| 21 | compatible = "amazon,al-fic"; |
| 22 | interrupt-controller; |
| 23 | #interrupt-cells = <2>; |
| 24 | reg = <0x0 0xfd8a8500 0x0 0x1000>; |
| 25 | interrupt-parent = <&gic>; |
| 26 | interrupts = <GIC_SPI 0x0 IRQ_TYPE_LEVEL_HIGH>; |
| 27 | }; |
